We have been given an equation of circle . We are asked to find the center and radius of the circle.
First of all, we will write equation of circle is standard form , where center of circle is at point (h,k) and radius is r.
Let us complete the square for both x and y.
Adding half the square of coefficient of x and y term, we will get:
Therefore, the center of the circle is and radius is 4 units.
Answer:
-3ab, -9x^2 -13x
Step-by-step explanation:
45a^4b^3 - 90a^3b/ 15a^2b
-45ab^2/15a^2b
-3ab
13) (x-7x^2) - (2x^2+14x)
-9x^2 -13x
The answer is B i think. i think you forgot the plus sign on B.
Please show a picture of the polygon then we will help
